Response

{
  "status": "success",
  "assigned": true,
  "phone_number_id": "3f1c2b9a-7d4e-4a21-9c33-0a1b2c3d4e5f",
  "phone_number": "+14155552671",
  "agent_id": "a1b2c3d4-e5f6-7890-abcd-1234567890ab"
}

Errors

400 — for invalid UUIDs; 404 if the number or agent does not exist; 409 if the number is already assigned to a DIFFERENT agent (unassign first); 502 if provisioning fails.

Notes

Assigning a number routes its inbound calls to the agent. Idempotent when re-assigning to the SAME agent (returns 200 with already_assigned: true).
